From my understanding in space-time everything moves at the speed of light $c$ in some direction of this four dimensional space. Light itself moves only through space, so it doesn't move at all in time. So if a photon is 'created' in the sun (I have no idea how that works and if it even makes sense for a photon to be 'created'), how can we see/perceive this photon? Because the photon must first travel the 8 minutes from the sun to the earth it must have been 'created' in the future, since at the instant we see it, it already traveled for 8 minutes, but also it didn't move through time. Is this correct? I find it difficult to understand how things that move through time interact with things that do not.

I think this is where your misunderstanding lies. In relativity, elapsed time depends on the reference frame in which it is measured. It is true that the proper time along a path followed by a light ray in vacuum is constant. So, relative to its own reference frame no time elapses for a photon, no matter how far it travels in space. But relative to any other reference frame the photon (in vacuum) travels a distance $d$ in time $\frac d c$ where $c$ is the speed of light. So the time taken relative to the Earth's reference frame for a photon to travel the eight light minutes from the Sun to the Earth is eight minutes.
